FIELD OF APPLICATION

This Utility Model patent application relates to a backpack that can beintended both for children and young people or adults.

PREAMBLE

This Utility Model patent application proposes a backpack intended forthe transport/storage of different kinds of objects, which may consistof school supplies, toys and others, if configured and intended forchildren, but can also be used for the transport/storage of any othertype of objects, if configured and intended for young people or adults.

The backpack object of this Utility Model patent application innovatesby presenting a design that allows the complete removal/replacement ofan integral part of its structure (a removable and replaceable frontportion).

STATE OF THE ART

The current state of the art pertaining to the subject matter of thisUtility Model patent application comprises a multitude of backpackmodels, which, depending on the target audience for which they areintended, may be designed with a configuration aimed at children, youngpeople or adults, further having with regard to backpacks for youngpeople or adults models that may have specific uses, such as, forexample, backpacks suitable for transporting equipment, such ascomputers and others, or models intended for use in extreme sports,camping and others.

In general, backpacks that were originally simple and unstructured bags,made of fabric and endowed with equally simple straps (almost alwaysmade with twines) and which had a top entrance opening also closed bytwine, are currently made up of a structured main body, usually made ofdurable fabric or other suitable material, on the rear face of whichadjustable straps, belts, etc., are arranged.

In today's backpacks, the main body can present pockets, compartments ora wide range of divisions, details and accessories that aim to maketheir use more practical and wider.

Usually, the main body of conventional backpacks further incorporates afront portion attached to the main body by a sector of fabric or othermaterial, which acts as a folding material to allow said front portionto be moved angularly to thereby open or close the backpack.

In conventional backpacks, the closing of the front portion regardingthe main body is usually done by using a fastener sector that can haveits slider pulled by a strap or pendant, one of the two sections of thefastener being sewn together along the edge of the backpack's main body,while the other section (complementary section) is sewn along the edgeof the front portion.

In this case, the fastener, which does not cover the entire perimeter ofthese two parts, begins and ends at the boundaries of the sector joiningthe main body and the front portion of the backpack.

Conventional backpacks are designed and manufactured so that their frontportion forms a cap-like part, which can be opened so that objects canbe placed or removed therefrom, not envisaging that such frontal portioncan be completely separated from the main body of the backpack.

PROBLEMS OF THE STATE OF THE ART

The backpacks belonging to the state of the art satisfactorily fulfilltheir basic function that consists in allowing a given volume of objectsto be transported and even stored therein.

In the case of backpacks intended for children, it is common thatdecorative patterns or those ones based on characters from the universeof children be added thereto, thus giving to such backpacks a playfuland child-friendly character.

It occurs that with time, past the initial moment and the novelty,children tend to lose interest in the theme with which the backpack isdecorated, a fact that may pose a problem.

Conventional children's backpacks do not allow, so to speak, that thetheme with which they are decorated can be changed later and, in thissense, parents are induced to acquire new models, which entailunnecessary costs and consequent premature disposal of the old backpackwhich, in many cases, may still be fully usable.

Thus, in the case of backpacks intended for children, they do not allowthe theme with which they were designed and produced to be changed laterat the child's request.

In the case of backpacks aimed at young people or adults, the thematicissue is not preponderant and therefore, the use of them can be extendedfor years.

Also, regarding these backpacks aimed at young people or adults, theyalso do not allow their configuration to be changed later or that theycan be customized for a specific use by replacing part of its structure.

OBJECTS

In view of the drawbacks noted in the prior art, it is one of theobjects of this Utility Model patent application to propose the backpackaddressed herein, which can be configured and intended for children,young people and adults, having this backpack its structure defined by amain body with adjustable straps attached to its rear face.

The backpack proposed herein has its main body designed and manufacturedto receive, through an innovative perimeter and integral fastener, theattachment of a removable and replaceable front portion.

It is a further object of this Utility Model patent application toprovide a backpack that incorporates a removable and replaceable frontportion that, in the case of models designed and configured forchildren, may be designed and manufactured to assume aesthetically adistinctive visual configuration, which may be allusive to an animal(stylized or not), child universe character, or other decorative elementof interest and thus may be replaced by another model of a removablefront portion with another distinctive visual configuration.

It is a further object of this Utility Model patent application toprovide a backpack that, in case it is intended for young people oradults, incorporates a removable and replaceable front portion, whichmay have assorted patterns and/or composition of compartments andaccessories, and may therefore be replaced by another model of removableand replaceable front portion with another pattern and/or composition ofcompartments and accessories.

It is a further object of this Utility Model patent application toprovide a backpack in which its removable and replaceable front portion,although fully detachable from the main body of the backpack, can beopened and closed thus allowing access to placing or removing objectsinside the backpack.

It is yet a further object of this Utility Model patent application toprovide a backpack that, by allowing its removable and replaceable frontportion to be completely separated from the main body, ensures that suchremovable and replaceable front portion can be replaced with anotherone, with another distinctive visual configuration (in the case ofbackpacks intended for children) or another with patterns and/orcomposition of compartments and accessories (in the case of backpacksintended for young people or adults).

Finally, it is yet a further object of this Utility Model patentapplication to provide a backpack that, by having a fully detachableremovable and replaceable front portion of its main body, can ensure theinnovative interchangeability condition between the main body anddifferent removable and replaceable front portions, thus enabling thechild, in the case of backpacks intended for children, to vary from timeto time, and to its own preferences, the differently themed frontportions, or in the case of young people or adults, the backpack can bealtered or customized by use of removable and replaceable front portionswith different patterns and/or composition of compartments andaccessories.

BRIEF DESCRIPTION OF INVENTION

The backpack presented in this Utility Model patent application isdefined, such as also verified regarding the backpacks belonging to thestate of the art, by a main body made of sturdy fabric, on the rear faceof which adjustable straps are arranged, said main body having a frontportion that can be opened or closed to allow objects to be placed orremoved from inside the backpack.

The backpack object of this Utility Model patent application, such asalso verified regarding backpacks belonging to the state of the art, hasa fastener as an element to allow closure of the front portion withrespect to the main body, differing, however, by the fact that in thepresent case, the front portion is a removable and replaceable frontportion and the fastener is of the perimeter and integral type,surrounding the entire perimeter of both the removable and replaceablefront portion itself and the contouring edge of the main body of thebackpack. Said integral perimeter fastener thus allows the removable andreplaceable front portion to be both open and closed, as is the casewith conventional prior art backpacks, but also allows the total andinnovative separation of that removable and replaceable front portionrelative to the main body.

In the backpack addressed herein, the removable and replaceable frontportion can be designed and manufactured for models intended forchildren, to present a distinctive visual configuration that can beallusive to an animal, a character of the children's universe or anyother decorative element of interest.

In the case of backpacks intended for young people or adults, theremovable and replaceable front portion can be designed and manufacturedto present a configuration with different patterns and/or composition ofcompartments and accessories.

DETAILED DESCRIPTION OF INVENTION

As illustrated by the above figures, the backpack presented herein,which is generally indicated by the numerical reference 1, is defined,such as also verified regarding the backpacks belonging to the state ofthe art, by a main body 2 made of sturdy fabric or other suitablematerial on the rear face 3 of which adjustable straps 4 are arranged,said main body 2 having a front portion which can be opened or closed toallow objects to be placed in or taken from inner space 6 of thebackpack 1. Said front portion, unlike the one verified with respect tothe state of the art, is a removable and replaceable front portion 5,delimiting the inner space 6 of the backpack 1.

The backpack 1 object of this Utility Model patent application, such asalso verified regarding the backpacks belonging to the state of the art,has a fastener as an element to allow the closure of the removable andreplaceable front portion 5 with respect to the main body 2, differing,however, by the fact that in the present case the fastener is aperimeter and integral type fastener 7, said perimeter and integralfastener 7 thus sewn so as to surround, respectively, all the perimeters8 and 9 of the contour edge 10 of the main body 2 and contouring edge 11of the removable and replaceable front portion 5, said perimeter andintegral fastener 7 thus allows the removable and replaceable frontportion 5 to be both open and closed, such as the backpacks belonging tothe state of the art, as also allows for innovative separation of theremovable and replaceable front portion 5 from the main body 2.

In the backpack 1 addressed herein, the removable and replaceable frontportion 5 may be designed and manufactured to present, in the case of amodel intended for children 1A, as depicted in FIGS. 1 to 8, adistinctive and differentiated visual configuration 12, which can eitherbe allusive to an animal, a children's universe character, or any otherdecorative element of interest.

In the case of the example depicted in FIGS. 1 to 6, the removable andreplaceable front portion 5 has a visual configuration 12 thatstylistically reproduces an alligator 13, said visual configuration 12includes a visual pattern print 13A referring to the face and belly ofthe animal and appliqués of 13B and 13C, respectively referring to thehind paws and teeth of the animal.

In the example depicted in this Utility Model patent application, theremovable and replaceable front portion 5 may be exchanged for anothermodel of removable and replaceable front portion 5, having a distinctiveand differentiated visual configuration 12 that stylistically reproducesa zebra 14, which includes visual pattern 14A printings referring to theanimal's face and coat pattern, and appliqués 14B referring to theanimal's ears.

The perimeter and integral fastener 7 has one of its sections (section15) sewn around the contouring edge 10 of the main body 2, while theother complementary section 16 is sewn around the contouring edge 11 ofthe removable and replaceable front portion 5 of backpack 1.

When the slider 17 of the perimeter and integral fastener 7, which ismounted in section 15, is coupled to the starting point 18 of section 16and is pulled in the closing direction, it causes the union of sections15 and 16 of said perimeter and integral fastener 7.

When the perimeter and integral fastener 7 is fully closed it causes thefull union of the removable and replaceable front portion 5 against themain body 2 of the backpack 1, whereas when fully opened it allows thetotal and innovative separation of said removable and replaceable frontportion 5.

On the other hand, when the perimeter and integral fastener 7 ispartially opened, leaving its extreme lower portion 19 (shown in FIG. 4only) together, it creates a bonding condition between the removable andreplaceable front portion 5 and the main body 2 of the backpack 1allowing said removable and replaceable front portion 5 to be moved inthe opening or closing direction of the backpack 1.

Although the starting point 18 of the perimeter and integral fastener 7appears positioned in the upper region of the removable and replaceablefront portion 5, which also corresponds to the upper portion of the mainbody 2, this starting point 18 may be positioned at other points of theperimeters of these two components, thus not being limited to thepositioning depicted.

The fact that the removable and replaceable front portion 5 is acomponent that can be completely separated from the main body 2 allowsthe same main body 2 to alternatively receive variants of suchcomponent, which variants may have quite different themes.

In the example depicted in FIGS. 6, 7 and 8, the removable andreplaceable front portion 5, by way of example, is characterized toappear as a decoration defining a visual configuration 12 thatstylistically reproduces an alligator 13, while the substitute version,and also by way of example, is characterized to appear as a decorationdefining a visual configuration 12 which also stylistically reproduces azebra 14, being the possibility of using other stylized animals ordifferent themes not ruled out.

In the aforementioned FIGS. 6, 7 and 8, it is presented the possibilityof total substitution of the removable and replaceable front portion 5model, characterized as an alligator 13 by the model characterized as azebra 14, characteristic that changes and renews the overall aestheticsof the backpack 1 and avoids having to replace it with another model atthe child's request. This possibility also allows the removable andreplaceable front portions 5 to be periodically alternated.

The focal point of this Utility Model patent lies precisely in thepossibility that the removable and replaceable front portion 5 can beused conventionally; being able to be opened and closed, as well, andinnovatively, it can be completely separated from the main body 2 andreplaced for another model with another theme, regardless the theme.

Following the same basic principle, but differently from the case ofbackpack model 1A that is intended for children, in variant model 1Bthat is intended for young people or adults, the removable andreplaceable front portion 5 does not have visual configuration 12 butrather a configuration 20 of patterns and/or composition of compartmentsand accessories 21.

In the example shown in FIG. 9, the removable and replaceable frontportion 5 is characterized, by way of example, to appear in aconfiguration with different patterns and/or composition of compartments21, having a single compartment of large volume 21A positioned in itslower region, while the substitute version, depicted in FIGS. 9 and 10,is characterized to appear, also as a mere object, in a configurationwith different patterns and/or compositions of compartments 21, havingthree smaller compartments 21B arranged side by side and positioned intheir lower region, while in its median region is foreseen a tiled area21C.

In the case of version 1B of backpack 1, the focal point of the presentUtility Model patent lies in the possibility that the removable andreplaceable front portion 5 can be used in a conventional way, whichmeans it can be opened and closed, as well as, and innovatively, it canbe completely detached from the main body 2 and replaced by anothermodel with another configuration (20) of patterns and/or composition ofcompartments and accessories, thus allowing the customization of theentire backpack.

Both in model 1A and variant model 1B, the herein proposed backpackinnovates before the previous copies belonging to the state of the artby allowing to obtain a completely new feature, which results from thepossibility of having an element of its structure (removable andreplaceable front portion 5) fully removed and exchanged for anothermodel with another theme, in the case of model 1A, or with anotherconfiguration (20) of patterns and/or composition of compartments andaccessories 21, in the case of variant model 1B.

This Utility Model patent application is not limited to the exemplarydrawing of main body 2, which may contain other styles andpresentations, and is not limited to the drawing presented herein.

It should be noted that the alligator and zebra figures presented hereinwith respect to model 1A are merely non-limiting examples of distinctiveand differentiated visual configurations 12 that the removable andreplaceable front portion 5 may have, and it is clear that the themecould be any theme belonging to children's universe, such as children'sstory characters, comic book heroes, etc.

It should also be noted that the backpack 1, concerning the models 1Aand 1B, although depicted as being made of fabric, with respect to boththe main body 2 and the removable and replaceable front portion 5, isnot limited to this type of construction since the innovative solutionpresented herein, namely the possibility of replacing the removable andreplaceable front portion 5 for another one with another theme (in thecase of the models intended for children) or with another configurationof patterns and/or composition of compartments (in the case of modelsintended for young people/adult or adults), can also be implemented inbackpacks that can be produced with rigid, molded, pressed, injected orother materials.

Specifically regarding the model 1B, it should be clarified that theconfigurations 20 depicted on the removable and replaceable frontportion copies 5 must be taken in a non-limiting manner as they may havea multitude of compartments and other accessories, therefore, thisUtility Model patent application is not limited to such examples.
